Like the Mage getting a glyph to get a polymorph: Penguin, I would love to see Druids get a minor glyph to change the appearance of Bear and Cat forms.
Cat:
Shadowmaw Panther
Stranglethorn Tiger
Winterspring Frostsaber
etc
Bear:
Black
Brown
Plagued Bear
Polar Bear - Already as a glyph, hoping more are added
etc
It would make telling one druid from another in raid easier and give us something that goes along with the new "hairstylist" stuff.
